Groundwater Vulnerability Zones

The Groundwater Vulnerability Maps can also be found on Defra's Magic Map from the Wednesday 9 August.

We are currently updating our groundwater vulnerability maps to reflect improvements in data mapping and understanding of the factors affecting vulnerability. The new maps will be released later in 2017.

The user guide outlines the kinds of activities the new maps can be used for.

These reports have been published on GOV.UK in advance of the release of the new maps to give users time to understand the new approach and how this differs from the previous groundwater vulnerability maps.
